Advanced electrode coating method for performance enhancement and lower production costs in Lithium Ion batteries
Agency / Branch:
DOD / MDA
An advanced method is proposed for applying very uniform electrode coatings for Lithium Ion batteries. The method will improve distribution of active material in the electrode for enhanced energy and power density and longer cycle life. With increased control of coating distribution and thickness, and elimination of waste, overall battery yield in manufacturing is expected to increase with a concomitant decrease in unit costs. The proposed method provides better separation of active material particles in the electrode matrix, so that each particle is fully wetted with electrolyte and in contact with conductive carbon particles to reduce internal resistance and insure that all active material is utilized in charge/discharge cycles.
